Wien bridge with asymmetrical supply

Normally, a Wien bridge
oscillator contains two identical
capacitors and two iden tical
(variable) resistors. That being
the case, the transfer factor of
the bridge is 1:3. For example,
when a potential of 1 V
is applied to the non-inverting
input of the opamp, the output
voltage of the amplifier will be
3 V.
